Abstract
ABSTRACT Wet blue leather was coated with a number of formulated solutions that contained urethane oligomer, acrylated monomers and dye. The coating was cured under UV radiation. Various rheological properties such as hardness, adhesion, tensile properties, water absorption, and gloss were studied. The effect of simulated weathering on these properties was also investigated. The treated leather gained enhanced tensile strength by 70% and elongation by 95%. The adhesion of the coating on leather was high (2.3 N/mm2) and the gloss was 75% with minimum abrasion. Water absorption was less than 4% by the coated leather surface. Polymer films were also prepared with the formulated solutions under the UV radiation. These films were characterized.
